Power Orc (5e Race Variant)
From D&D Wiki
Power orcs are known as "lightning-struck" orcs. It is said that sometimes, lightning will strike one of their members in a form of test by Gruumsh. This was a popular idea back when Talos was still seen as an aspect of Gruumsh. Nowadays, this is less so. There remain legends of these powerful orcs that were struck by storm and came to wield its strength... though few can say if these are tall tales or fact. To wield such power takes a strong body, and not all are capable of surviving its tolls.
This race variant replaces the Primal Intuition trait. You instead gain the Lightning-Infused trait.
Lightning-Infused. You know the shocking grasp cantrip. At 5th level, you can use the call lightning spell once, casting it at its lowest level. You regain use of this spell after you finish a long rest. Constitution is your spellcasting modifier for these spells.
